OVERHEAD SUPPORT FOR CONDUCTING-WIRES (lF CLOTH CUTTING- MACHINES.

E EGIFIGATION forming part of Letters Patent No. 508,534, dated November 14, 1893.

Application filed March 10,1893. SerialNo. 465,451. (No model.) i

To all whom it may concern.-

Be it known that I, ARTHUR K. THYLL, a subject of the Emperor of Austria-Hungary, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Overhead Supports for the Electric Conducting-Wires of Cloth- Cutting Machines, of which the following is a specification.

This invention relates to an improved overhead support for the conducting wires of electric motors, cloth cutters and similar devices, in which it is necessary that the conducting wires follow the motion of the motors to which the current is supplied; and the invention consists of an overhead support for electric conducting wires which is swiveled to the ceiling of the room or to a suitable hanger, the spindle of the bracket being made hollow and provided with non conducting heads so as to permit the conducting wires to pass through the hollow spindle of the swivel to a connecting piece attached to the ceiling. To the outer end of the bracket is attached a guide-roller over which the conducting wires pass While a tension weight is supplied to the wires between the guide-roller and the spindle of the bracket, by which the tension of the conducting wires is regulated and the latter adapted to follow the motion of the motor to which the current is to be supplied. 7

In the accompanying drawings, Figure 1 represents a side-elevation of my improved overhead support for electric conducting wires, showing the wire connected by an electric cloth-cutter. Fig. 2 is aside-elevation of the overhead support drawn on a larger scale, and Fig. 3 is a horizontal section of the same,

. on line 3 3, Fig. 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a hanger that is made of suitable cast metal, and which is attached to the ceiling or other point of support. .At the center of the hanger is supported the hollow spindle B of a bracket 7 lower ends of the hollow spindle B are provided with rounded off hard rubber or other non conducting heads (1d, the upper head serving to support the swivel spindle B, while the lower head serves to support the sleeve d that is interposed between the lower lug of the bracket C and the'lower head at of the spindle B, the sleeve cl serving to take up the friction between the bracket and the spindle. Above the hanger is arranged on the ceiling the usual connection E for conducting wires which is made of porcelain or other suitable non conducting material. The conducting wires e extend from the connecting piece E through the hollow spindle B, and pass from the lower end of the spindle over a guidepulley C that is attached to the outer end of the bracket C to the motor of an electric cloth cutter H or any other device. Between the spindle B and the guide-pulley C is arranged on the conducting wires a tension weight D, which moves readily over the conducting wires by a guide-pulley D which is supplied to the forked upper part of the tension weight D which is raised or lowered according to the motor, to which the current is supplied is moved either under the bracket or outside of the circle which is described by the swinging bracket. The tension weight keeps the conducting wires taut by taking up the slack in the same, so that the motor can be moved in any direction, while by the swivel connection of the bracket with the hanger and the tension weight, the conducting wire can be moved in every direction over the table or other support on which the cloth cutter or other device is operated. There is consequently no interference with theelectric conducting wire, so that no short circuiting or other inconvenience or interruption of the working of the cloth cutter or other device cantake place.

Having thus described my invention, I

claim as new and desire to secure'by Letters Patent- 1. An overhead support forthe electric conducting wires of cloth-cutting machines, composed" of a hanger attached to a suitable support, a hollow spindle supported on said hanger, and a horizontal bracket that is swiveled to said spindle and provided with a guidepulley at its outer end, and conducting wires provided with a guide-pulley for moving over passing through the hollow spindle, substanthe conducting wires and keeping the same tially as set forth. taut, substantially as set forth.
